	Optimal bandwidths are calculated using the rdob command.
	
	Taking the variable "growth" as an example, the command line is as follows:
		
		rdob growth running, c(2.3) fuzzy(treated)
	
	The output is as follows:
		
		optimal bandwidth(h_opt) = 1.5031105
	
	So we set optimal bandwidth for the variable "growth" to 1.5031105.
